At 10:58 CET (Dec. 05) I had the IP 84.149.167.143 and sent following query: "-k 84.149.167.143\n". I also tried to send "-k 84.149.167.143\r\n" and "-k 84.149.167.143" before. After each query the connection has been closed. I used following c# code: <blockquote type="cite"> ... try { /* Connecting to server (will crash if address/name is incorrect) */ myClient = new TcpClient("whois.ripe.net", 43); /* Store the NetworkStream */ myStream = myClient.GetStream(); /* new Text Stream Reader */ reader = new StreamReader(myStream); /* new Text Stream Writer*/ writer = new StreamWriter(myStream); } catch (Exception e) { Exception e2 = new Exception("could not connect to server\n" + e.Message); throw e2; } ... //send query to RIPE DB writer.WriteLine("-k 84.149.167.143\n"); writer.Flush(); //read RIPE DB query response string response = ""; while (!reader.EndOfStream) { response += reader.ReadLine() + "\n"; } </blockquote> Greetings Sepp <blockquote cite="mid20061206094553.GC15757@ripe.net" type="cite"> <pre wrap="">On Tue, Dec 05, 2006 at 04:48:28PM +0100, Sepp wrote: Dear Sepp, It looks like your tool sends some broken query at some point, hence the error 'No search key specified'. Try printing out the complete debugging output of what your tool sends to the whois server, and let us know. From which IP address are your querying? We might check our log files to see which queries exactly did our server receive from your IP. Katie Petrusha RIPE NCC </pre> <blockquote type="cite"> <pre wrap="">Hello all, attention bad english ahead! ;-) I'm writing a tool which queries the RIPE DB to find out the location of some IP adresses. When I query the database with a string like "84.149.135.10/16\r\n", i get a correct response and the tcp/ip connection will be closed by RIPE. But because I've to query some more IPs, i would like to let the connection open. As i read in the RIPE DB manual there is the "-k" flag which should tell the DB letting the connection open until I send an empty query. In telnet it works fine, but not in my tool. In my tool i'm sending a string like "-k 84.149.135.10/16\r\n" (in telnet i wrote "-k 84.149.135.10/16" + <return>).
